Mercury.
For those in 'Nairo' is to perhaps alert them, and of just whom they are, and as Evolutionary beings in many a way too. That in all truly, it was mentioned before that, evolution in 'Nairo', is targeted towards becoming as pure as possible, and this in many a way even, does speak of Sainthood in itself actually. In all, when those in 'Nairo', do think of whats most perfect of all things in all (and as with speak even of pureness in itself), then let it in all again, either match, or go along with Red Mercury that is [and as with Red Mercury too, perceived in all as being the most perfect of substances, and that those in 'Nairo' in all again, are very much evolving and in matter and blood too, and into something similar in all, and to Red Mercury that is] [in all again, that which does match Red Mercury can be said to be permanent to 'Nairo' in all, while that which does go along with Red Mercury, can be said to be partial/temporary, and to 'Nairo' in itself too that is].
